High Performances Analog Front-End for Integrated BiCMOS Streak Camera

This work presents the development of a 400pixel solid-state streak camera, designed in 0.13μm BiCMOS technology, with a focus on enhancing the front-end architecture to push analog performance across all channels. The sensor achieves a framerate of 10 Gfps and a total sampling rate of 4 Terapixels/s, utilizing a novel integrated Streak architecture. Each of the 400 integrated photodiodes is connected to a highperformance wide-band transimpedance amplifier, delivering 92 dB of gain and 3 GHz of bandwidth, far exceeding what is reported in the current literature. While the sweep speed of 100 ps is in line with state-of-the-art systems, the exceptional front-end performance marks a significant advance. The design also incorporates a 400-point deep analog on-chip memory for burst imaging and includes a post-trigger functionality to resolve synchronization challenges during event recording.
